ABSTRACT
Carl R. Rogers (1942, 1951, 1957, 1959) developed a theory of psychotherapy that impacted the fields of counseling and psychotherapy in an unprecedented way. He was the first psychotherapist to extensively tape record counseling interviews, and the first psychologist to thoroughly investigate the process of psychotherapy using the scientific method of research. His efforts revolutionized the field of psychotherapy by de-mystifying it, and by opening up psychotherapeutic practice to professionals other than psychiatrists. The work of Rogers, however, had a penetrating influence. The principles that he hypothesized, first, in the field of psychotherapy were applied to a wide span of areas that included group work, education, international conflict mediation, and career counseling.
